Cymbidium White Mold in Pot: Decomposed Mix, Spike Risk, and Test Plant Strategy

White Mold = Overly Wet, Decomposed Mix

White fungal growth throughout half the pot = mix broken down to soil-like consistency, holding water, blocking air. Dark leaf spots = water on leaves overnight.

Risky to Repot With Spikes

Test one plant first: soak fresh mix overnight, drain, repot carefully preserving spike. Watch 1-2 weeks. If spike grows normally, repot others. If spike stalls, wait until after bloom.

Leaf Spot Management

Cut leaves below black spots. Water/feed early morning only to prevent new spots.
